XRandR: Screen Rotation animation effect

Currently, when we use Xrandr to rotate the screen, the screen goes blank
for a second or two and then shows the screen in the new orientation. I was
exploring if it was possible to avoid the flicker and substitute it with a
relevant animated effect - Is this code change even do-able, given the way
xserver interfaces with the video drivers? Any pointers?

The alternative would be not to use XRandR at all, and let the window
manager do the effect - but this requires the Input redirection patches
(which has limitations)
